ATLANTA (AP) -- Tooth decay in young children's baby teeth is on the rise, a worrying trend that signals the preschool crowd is eating too much sugar, according to the largest government study of the nation's dental health in more than 25 years.
The study also noted a drop in the proportion of non-elderly adults who have visited a dentist in the past year - a possible indicator of declining dental insurance.
But there was some good news: Older children have fewer cavities and adults have less periodontal disease than in the past, and more of the elderly are retaining their teeth.
"Overall, we can say that most Americans are noticing an improvement in their oral health," said the study's lead author, Dr. Bruce Dye of the National Center for Health Statistics.

Critical review: Updated recommendations for the prevention, diagnosis, and treatment of osteonecrosis of the jaw in cancer patients—May 2006
Crit Rev Oncol Hematol. 2007 May;62(2):148-52
Authors: Weitzman R, Sauter N, Eriksen EF, Tarassoff PG, Lacerna LV, Dias R, Altmeyer A, Csermak-Renner K, McGrath L, Lantwicki L, Hohneker JA
In light of recent reports of osteonecrosis of the jaw (ONJ) in cancer patients whose treatment regimens include an intravenous bisphosphonate, Novartis convened an international advisory board of experts in the fields of oral surgery and pathology, medical oncology, metabolic bone disease, and orthopedics to review existing data and provide updated recommendations on the clinical diagnosis, prevention, and management of ONJ in the oncology setting. Recommendations were developed to help guide healthcare professionals in early diagnosis and patient management. It is recommended that patients be encouraged to receive a dental examination prior to initiating bisphosphonate therapy and, if possible, complete any necessary dental procedures (e.g., tooth extraction) prior to initiating bisphosphonate therapy. Patients should receive regular dental visits during bisphosphonate therapy. Patients should be encouraged to practice good oral hygiene and minimize possible jaw trauma. If possible, patients should avoid dental surgery during treatment with bisphosphonates. If exposed bone is observed or reported in the oral cavity at any time (suspected ONJ), refer the patient to a dental professional immediately.

The guidance to dentists follows on from precautionary advice from the Spongiform Encephalopathy Advisory Committee to the Department of Health and early results from ongoing research conducted by the Health Protection Agency, indicating a potential risk of vCJD associated with endodontic procedures.
Dr Barry Cockcroft said:
"There are no reported definite or suspected cases of vCJD transmission arising from dental procedures - this new guidance to dentists is purely an extra precaution. The public should continue to attend their dentist as normal."
1. The guidance applies to all primary and secondary care dentists in England.
2. Endodontics relate to treatment to the dental pulp of a tooth. A major part of this is root canal work. No other aspect of dental work is affected by this precautionary advice.
3. There are approximately 1 million NHS endodontic treatments every year in England and Wales. Since 1996 there have been 165 cases of vCJD. There is no current evidence of vCJD being transmitted by any form of dentistry.
4. Variant Creutzfeldt-Jakob Disease (vCJD) is one of the Transmissible Spongiform Encephalopathies, the group of prion diseases that include Bovine Spongiform Encephalopathy (BSE), Creutzfeldt-Jakob Disease (CJD), and scrapie.
5. This letter reflects precautionary advice from the Spongiform Encephalopathy Advisory Committee (SEAC) and early results on the potential infectivity of dental tissues from research in progress by the Health Protection Agency. This research supports the view that dental instruments (files and reamers) used in root canal treatment could possibly pose an effective route of vCJD transmission.
6. Almost everyone is at some risk of being infected with vCJD due to dietary exposure to BSE. Any additional risk from a root canal treatment could only arise if the instruments had been previously used on an infective patient. The proportion of people carrying infection is highly uncertain. Published information suggests that this may be between 1 in 1,400 and 1 in 20,000 people, though it may well be less for some age groups. It is also not clear how many of those carrying the infection are likely to develop symptoms of vCJD: given the much smaller number of cases actually seen so far, the majority may never do so (Clarke and Ghani, 2005). Even if instruments had been used on someone carrying the infection, it is not clear how great the risk of vCJD being passed on would be. Nevertheless, a precautionary approach is justified in view of the number of endodontic procedures carried out.

Over the last decade, scientists have assembled the complete DNA sequences of several important members of the oral biofilm, from Streptococcus mutans to Porphymonas gingivalis to Treponema denticola. In the April issue of the Journal of Bacteriology, NIDCR-funded investigators have added another big name to the list. It is the bacterium Streptococcus sanguinis, an early colonizer of the dental pellicle and a key player in the formation of the oral biofilm. Although not regarded as a pathogen in the mouth, S. sanguinis is known to enter the bloodstream, where it has a propensity to colonize the heart valves and contribute to bacterial endocarditis, a condition the kills an estimated 2,000 Americans each year. With the bacterium’s genetic blueprint now publicly available online, scientists can better study the dynamics of biofilm formation and possibly tease out new leads to prevent tooth decay and periodontal disease. They also now can systematically identify and exploit the weak spots written into the DNA of S. sanguinis, invaluable information in designing more effective treatments for endocarditis.

"This number comes as a surprise considering today's seniors are keeping more and more of their natural teeth," says Dr. Jack Cottrell, president of the Canadian Dental Association. "We absolutely can keep our teeth healthy for a lifetime - it just looks like attitudes may have to catch up with the new reality."
In fact, more than half of the survey respondents have more than 75 per cent of their natural teeth. Other results of the survey paint a picture of an aging population in which the value of oral health is growing, and the results are starting to show. Eighty-two per cent of respondents rated their oral health as good to excellent; 84 per cent do not feel self-conscious about the state of their teeth; and 83 per cent are able to make varied food choices.
In addition, most seniors reported making at least annual visits to the dentist. "Regular dental visits are especially important as we age." said Dr. Cottrell, "During your check-up, your dentist is doing a lot of things in addition to checking your teeth and gums - like screening for signs of oral cancer, talking to you about the possible oral effects of medications you may be taking, and explaining the relationship between oral health and overall health."
A recent study in the Journal of the Canadian Dental Association shows gum disease may be more prevalent among diabetic patients than non-diabetics, and may actually contribute to the likelihood of developing the disease.
"Gum disease and diabetes create a vicious circle - the disease cycle of each negatively affects the other," says Dr. Cottrell. "Since the risk for both diseases increases as we age, your dentist is a vital part of your complete health."

CHICAGO, April 20, 2007—Detection of calcified tissue in the carotid artery by dental x-rays is not enough evidence to estimate a patient’s stroke risk was the conclusion of a systematic literature review published in this month’s Journal of the American Dental Association (JADA).
Stroke is one of the leading causes of death and disability among adults in the U.S. It occurs when a blood vessel that brings oxygen and nutrients to the brain bursts or becomes clogged by a blood clot or some other mass.
Panoramic radiography is a procedure used in dental practice for detecting dental disease. According to the JADA article authors, a trend toward using panoramic x-rays to identify stroke-prone patients has become a much-debated health care issue over the past two decades.
In their literature review, the authors conducted an electronic search using 11 databases to evaluate evidence that links calcified carotid artery atheroma (CCAA) detection on panoramic radiographs and the precipitation of cerebrovascular accidents (CVA). The search identified 54 articles for the review. Only one study satisfied the authors’ inclusion criteria and found no significant difference in the incidence of cerebrovascular diseases between subjects with CCAA and subjects without CCAA.

Two studies look at the possible connection periodontal bacteria may have with other systemic conditions
CHICAGO—April 10, 2007—Two new studies in the Journal of Periodontology explore the possible link between periodontal bacteria and
Periodontal bacteria have often been thought to play a role in many of the possible connections between oral health and overall health. Two of the studies in this month’s issue of the JOP further the understanding of these potential connections. One study looked at patients who had been diagnosed with coronary artery disease and examined the bacteria found in their arteries. They were able to identify periodontal pathogens in the coronary and internal mammary arteries in
A second study looked at women who had suffered from preeclampsia during their pregnancy, a condition characterized by an abrupt rise in blood pressure that affects about 5% of pregnancies. The study found that
“These studies are just a few in the growing body of evidence on the mouth-body connection. More research is needed to fully understand how periodontal bacteria travels from the mouth to other parts of the body as well as the exact role it has in the development of these systemic diseases,” said

New guidelines for prevention of infective endocarditis were released by the American Heart Association April 19. The AHA and ADA now recommend that fewer dental patients with heart disease receive antibiotic prophylaxis before dental procedures to prevent the heart infection called infective endocarditis (IE). The guidelines were developed by a group appointed by the AHA that included experts in infectious disease and cardiology and members representing the ADA. The guidelines were endorsed by the Infectious Diseases Society of America and the Pediatric Infectious Diseases Society.
After reviewing relevant scientific literature from 1950–2006, the group concluded that bacteremia resulting from daily activities is much more likely to cause IE than bacteremia associated with a dental procedure. In addition, only an extremely small number of IE cases might be prevented by antibiotic prophylaxis, even if prophylaxis is 100% effective. Based on these conclusions, antibiotic prophylaxis is now recommended before dental procedures only for patients with underlying cardiac conditions associated with the highest risk of adverse outcome from IE, such as patients with artificial heart valves, a history of endocarditis, certain serious congenital heart conditions and heart transplant patients who develop a problem with a heart valve.
The guidelines say patients who have taken prophylactic antibiotics routinely in the past but no longer need them include people with:
* mitral valve prolapse
* rheumatic heart disease
* bicuspid valve disease
* calcified aortic stenosis
* congenital heart conditions such as ventricular septal defect, atrial septal defect and hypertrophic cardiomyopathy.

More on the Frequency of Oral Bisphosphonate-Associated Osteonecrosis of the Jaw: A New Report from Australia
Researchers at the Adelaid Dental Hospital at the University of Adelaid in South Australia have estimated that the total number of patients on oral bisphosphonates to treat osteoporosis over a two-year period in Australia was 304,900. The total number of patients identified with osteonecrosis of the jaw (ONJ) taking bisphosphonates for osteoporosis was 36, giving an overall frequency of ONJ of 1 in 8,470. The overall frequency of dental extraction-related ONJ in osteoporosis patients was 1 in 1,130.

The prevalence of myofascial pain and its association with occlusal factors in a threshold country non-patient population
Abstract The objective of the study is to assess the prevalence of myofascial pain in a threshold country and to isolate occlusal risk factors. One hundred and seventy-one randomized selected women were examined by a trained examiner in accordance with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) examination procedure. Subscales of the SCL 90-R, graded chronic pain status, and anamnestic questionnaires were also used. Logistic regression was performed to compute the odds ratios for six common occlusal features with regard to the presence of myofascial pain, in accordance with the RDC/TMD criteria. Fifteen subjects (15 / 151 = 9.93%) suffered from myofascial pain. Results from logistic regression analysis showed that non-occlusion (posterior teeth, at least one side) and open bite increased the risk of myofascial pain. The prevalence of myofascial pain in this study is comparable with that in another study, in a highly industrialized environment, in which the RDC/TMD was used. The role of occlusion in a non-patient population seems to be restricted to serious alterations of normality. This article presents the prevalence of myofascial pain and its association with occlusal factors. This issue will help the clinicians to assess the influence of occlusion in myofascial pain patients and to send the patient to the appropriate specialist.

WASHINGTON -- A federal appeals court said Friday it could not force
the Food and Drug Administration to tighten restrictions on dental
fillings containing mercury.
Advocacy groups sought to ban the use of such fillings and to force
the FDA to classify them as risky, subjecting them to tougher
The groups say the fillings pose health risks to patients who inhale
mercury vapors and dental office employees who handle the materials.
The U.S. Court of Appeals for the District of Columbia Circuit
unanimously ruled that, while certain FDA actions can be appealed, the
court has no jurisdiction to review agency inaction.
The mercury mixture has stirred controversy since dentists began using
it to fill cavities in the 1800s. Significant levels of mercury
exposure can cause permanent damage to the brain and kidneys, but the
FDA has said for years that mercury fillings don't harm patients,
except in rare cases when they have allergic reactions.
Amalgam fillings are about 50 percent mercury, joined with silver,
copper and tin. Tens of millions of Americans receive mercury fillings
each year. Many doctors have begun switching to resin composite
fillings that blend better with the natural coloring of teeth.
Federal health officials began a new review of the safety of the
fillings last year.

The finding is reported in the March issue of the Journal of Urology by a team from the University of Pittsburgh School of Dental Medicine, in Pennsylvania.
"Urologists and oncologists, in particular, should heed these findings and refer their patients for periodontal screening early in the course of their ADT," commented lead author Pouran Famili, DMD, PhD. This early referral is standard for other groups of at-risk patient populations, such as transplant recipients, he pointed out.
The study found that men with prostate cancer on ADT were 3 times as likely to show signs of periodontal disease as a similar group of men with prostate cancer who were not receiving such therapy. The comparison was based on 68 men, of whom 41 had received ADT for an average of 18 months. The majority of these men (80%) had periodontal disease, the researchers report. In contrast, only 4% of the men not receiving ADT had periodontal disease.
"To our knowledge, this is the first report of a high prevalence of periodontal disease in men on ADT," the researchers comment. "If confirmed in other, larger studies, this observation could have major public health consequences, given the increasing number of men with prostate cancer and the increasing use of ADT to treat these men." They note that prostate cancer is being diagnosed at an earlier stage, and ADT is being administered earlier in the course of the disease. Many of these men survive for years after the diagnosis, and as a result, can end up taking ADT for prolonged periods.
In their study, most of the men in the group taking ADT who were found to have periodontal disease were "highly educated, visited the dentist regularly, and had good plaque control," the team writes in the paper. Commenting further in a press statement, Dr. Famili said: "As the majority of these men were quite conscientious about their oral hygiene, the need for early intervention by a dental care provider is paramount. It could prevent the need for more extensive treatment down the road. "
The team speculates that the association between periodontal disease and androgen deprivation may be due to osteoporotic bone loss as a result of the therapy. They note that previous studies have reported that ADT can cause a severe bone loss and osteoporosis, and they speculate that ADT may enhance rapid bone loss around the teeth and may initiate or accelerate periodontal disease despite good plaque control.
"Because ADT is needed to treat prostate cancer but has a negative impact on dental health, oncologists must be aware of this to encourage dental care and follow-up," the team concludes.

Periodontal pathogen detection in gingiva/tooth and tongue flora samples from 18- to 48-month-old children and periodontal status of their mothers
Oral Microbiol Immunol 2002: 17: 55–59.© Munksgaard, 2002.
Few studies have detected periodontal pathogens in young children, and when detected the prevalence has been relatively low. In this epidemiological study, we determined the prevalence of periodontal pathogen colonization in young children and examined the relationship between periodontitis in mothers and detection of periodontal pathogens in their children aged 18–48 months. Children were selected and enrolled randomly into the study; tongue and gingival/tooth plaque samples were harvested and analyzed by DNA probe checkerboard assay for Porphyromonas gingivalis and Bacteroides forsythus. Clinical measurements included a gingival bleeding score in the children and a periodontal screening and recording (PSR) score in the mothers. Mothers having one or more periodontal sites with probing depths > 5.5 mm were classified as having periodontitis. In this population, 71% (66/93) of the 18- to 48-month-old children were infected with at least one periodontal pathogen. Detection rates for children were 68.8% for P. gingivalis and 29.0% for B. forsythus. About 13.8% (11/80) of children had gingival bleeding in response to a toothpick inserted interproximally. Children in whom B. forsythus was detected were about 6 times more likely to have gingival bleeding than other children. There was no relationship between bleeding and detection of P. gingivalis. 17.0% (16/94) of the mothers had periodontitis. When all mother–child pairs were considered, the periodontal status of the mother was found not to be a determinant for detection of periodontal pathogens in the floral samples from the children. However, the odds ratio that a daughter of a mother with periodontitis would be colonized was 5.2 for B. forsythus. A much higher proportion of children in this population were colonized by P. gingivalis and/or B. forsythus than has been previously reported for other populations. A modest level of association between manifestations of periodontitis in mothers and detection of B. forsythus in their daughters was observed.

For all of those that have an intermittent triggering of the EVA sensors, there is an update that is important to download. That means that once in a while you expose the sensor and nothing happens, it still says “Ready To Take X-Ray” in the red box in the chart template. It is as if the sensor did not receive x-ray, though you did push the x-ray button.
The driver update makes EVA more sensitive to x-ray. You may also notice that the exposure times lower slightly. That is a good thing, but it may take a couple of shots to get used to the new settings.
PLEASE follow the directions as they are written below. You will NOT install all of the pieces that you will download. This is quite important.
*** And, if you are not going to read the directions but you are going to install the update, please just make sure that you DO NOT INSTALL THE TWAIN DRIVER. ***

If you do any sleep apnea cases this may be of interest to you.
Obstructive sleep apnea (OSA) and the spectrum of sleep disorders are significantly underdiagnosed but repeatedly associated with increased risk for heart attacks and strokes. The difficulty in diagnosing OSA is due in part to the expensive and cumbersome test required for an accurate diagnosis. One company, CleveMed, is hoping to change that with their new virtual sleep study device that claims to be a blend of quality and convenience. Cleveland Medical Devices Inc. (CleveMed) announced today that it recently conducted the first virtually attended sleep study using mobile phone broadband internet service from a subject's home. The study was performed using CleveMed's proprietary wireless technology and medical communication system to provide real-time transmission of polysomnography (PSG) data. This new technology combined with CleveMed's established wireless PSG systems can now allow a technologist to perform virtually attended sleep studies from almost anywhere in the world.

CHICAGO (March 8, 2007) — Bisphenol A (BPA) is widely used in the manufacture of some types of plastics, primarily for consumer products. Concerns have been raised about the safety of such widespread use of BPA in consumer products, because laboratory testing has suggested that it may affect reproduction and development by mimicking the effects of the female hormone estrogen. To date, these effects observed in laboratory animals have not been observed in humans.
Humans are exposed to BPA through its use by the food industry in the manufacture of epoxy resins that coat cans and polycarbonate bottles that hold foods and beverages. It is also used in the manufacture of some children’s toys, plastic tableware and infant bottles. BPA is also released to the environment in industrial and household wastes. Although BPA is not an ingredient in either dental product, there is some evidence that some dental sealants and to a lesser extent composites may contribute to low-level BPA exposure, probably through the action of salivary enzymes on a minor ingredient.
The ADA sees no cause for concern at this time regarding potential BPA exposure from composites or sealants. The presence of a substance in the environment or in human blood or urine samples does not mean that that substance is necessarily causing harm. Whether or not a substance is harmful to human health depends upon how much of the substance we are exposed to. Virtually any substance can have a harmful effect at high doses – even water and vitamins.
Nevertheless, the ADA supports additional research into how much BPA people are actually exposed to and at what levels of exposure health effects start to occur.
The U.S. Department of Health and Human Services (HHS) has commissioned a report on the chemistry of BPA, its intended uses and sources of human exposure. Additionally, the agency has convened an independent panel to review the results of the report. These are important steps toward identifying the potential for any health and/or environmental concerns.
As the professional association of dentists committed to the public's oral health, the ADA is greatly interested in the results of the report. The ADA looks to the HHS to provide scientific guidance on issues that affect the health of Americans.

ALBUQUERQUE, N.M. — Who would have guessed that when the Star Trek medical diagnostic tool known as the tricorder makes its appearance in real life, the first user might be . . . your dentist.
According to a paper in the March 27 issue of PNAS (the Proceedings of the National Academy of Sciences), a recently completed pilot study conducted with the University of Michigan shows that a Sandia National Laboratories handheld device determined in minutes — from a tiny sample of saliva alone — not only if a patient has gum disease but quantitatively how advanced the disease is.
“The gold standard for any medical test is when instruments are used to examine human patients,” says Sandia researcher Amy Herr. “The pilot study allowed us to compare our results to accepted clinical measurements. Then we could statistically validate both the periodontal disease biomarker and the new microfluidic instrument.
“We achieved faster and more reproducible results because we combined steps that ordinarily require time-consuming manual handling by many people, into a single automated device.”
Using a disposable lab-on-a-chip cartridge, the device makes use of a molecular sieve made out of a polyacrylamide gel. The location of the sieve in the microfluidic chips is determined using photo-lithographical methods adapted from the semiconductor industry. The gel is porous, with very small openings. A low electrical current (measured in micro-amps) is passed through the gel and a process called electrophoresis moves charged proteins through it. The gel has a gelatin-like consistency and, by permitting the easy passage of smaller molecules and slowing the passage of larger ones, quickly separates proteins contained in the saliva. Prior to this separation, the proteins are brought into contact with specific antibodies chosen on their ability to bind to the biomarkers. The antibodies are pre-labeled with fluorescent molecules attached to them. Interrogation by laser of these combined molecules — fluorescent antibody and fluorescent antibody bound to the biomarker — determines the amount of biomarker present, indicating the degree of periodontitis.Read the entire press release by clicking here.

Vitamin C from dietary sources, but not from supplements, is associated with a reduced risk of oral pre-malignant lesions in men, a new study indicates.
Dr. Nancy Nairi Maserejian, of New England Research Institutes, Watertown, Massachusetts, and colleagues examined intake of vitamins C, E, A and carotenoids in 42,340 men enrolled in the Health Professionals Follow-up Study and the occurrence of oral pre-malignant lesions. The men provided information on supplement use and diet every 2 to 4 years.
A total of 207 oral premalignant lesions were diagnosed between 1986 and 2002, the team reports in the International Journal of Cancer.
The risk of developing such a lesion was not significantly linked to total intake of vitamin C, vitamin A, or carotenoids. However, dietary vitamin C was significantly associated with a reduced risk of oral premalignant lesions: those with the highest intake had a 50 percent reduction in risk compared to those with the lowest intake.
The researchers found no clear relationship with beta-carotene, lycopene, or lutein/zeaxanthin. A trend for increased risk of oral pre-malignant lesions was observed with vitamin E, especially among current smokers and with vitamin E supplements. Beta-carotene also increased the risk among current smokers.
"It is possible that the protection that seems to be offered by dietary intake of vitamin C is actually partly due to some other component of vitamin C-rich food," Maserejian said in an interview with Reuters Health.
"Although we do not yet know exactly what component -- or interaction between components -- is most important, a diet that includes vitamin C-rich foods as well as a variety of nutrients is likely to benefit most people," she said.
"Our results also highlight the need to consider possible harmful effects of high doses of vitamin E supplements among smokers," the researcher noted.

Exposing teeth to soft drinks, even for a short period of time, causes dental erosion—and prolonged exposure can lead to significant enamel loss. Root beer products, however, are non-carbonated and do not contain the acids that harm teeth, according to a study in the March/April 2007 issue of General Dentistry, the AGD’s clinical, peer-reviewed journal. That might be something to consider during the next visit to the grocery store.
Consumers often consider soft drinks to be harmless, believing that the only concern is sugar content. Most choose to consume “diet” drinks to alleviate this concern. However, diet drinks contain phosphoric acid and/or citric acid and still cause dental erosion—though considerably less than their sugared counterparts.
“Drinking any type of soft drink poses risk to the health of your teeth,” says AGD spokesperson Kenton Ross, DMD, FAGD. Dr. Ross recommends that patients consume fewer soft drinks by limiting their intake to meals. He also advises patients to drink with a straw, which will reduce soda’s contact with teeth.
“My patients are shocked to hear that many of the soft drinks they consume contain nine to twelve teaspoons of sugar and have an acidity that approaches the level of battery acid,” Dr. Ross explains. For example, one type of cola ranked 2.39 on the acid scale, compared to battery acid which is 1.0.
Researchers concluded that non-colas cause a greater amount of erosion than colas. Citric acid is the predominant acid in non-cola drinks and is a major factor in why non-cola drinks are especially erosive. There is a significant difference between sugared and diet colas.
“The bottom line,” Dr. Ross stresses, “is that the acidity in all soft drinks is enough to damage your teeth and should be avoided.”
